Quoted from fooflighter:Just FYI I did not use metal washers on top of the petg I think those will add too much pressure and you're going to now create a larger circle of pooling... Again your mileage may vary I'm just saying what I've experienced over 1,700 plays using posts on bare PETG with no metal washer. The point of using the petg was that it was rigid but yet slightly flexible to allow some give at the edges I'm afraid a metal washer is going to force down too much of that contact surface and you're going to create a larger problem over time... just my opinion though
I used the metal washer on all of them that had metal washers. I am a but nervous about the torque and if I over torqued. I really did try to NOT over do it, but I think tomorrow I'm going to loosen them just a little.
